Description

  The present invention mainly relates to a charging stand for setting and charging an electric device such as a mobile phone.

  The charging stand includes positive and negative output terminal portions that are in contact with the charging terminal of the electric device to be mounted. When a metal comes into contact with the positive and negative output terminals and shorts, a large short current flows. In addition, when the voltage at the positive and negative output terminal portions is high, there is a possibility of electric shock when touched with wet hands. Even if the voltage is low, there is a risk of low temperature burns if contacted for a long time. In order to eliminate this adverse effect, a charging stand has been developed in which the output terminal portion is accommodated in the case in a state where no electrical device is mounted (see Patent Document 1).

  The charging stand described in this publication is shown in FIGS. The charging stand includes a case 31 having a concave mounting portion 32 that fits and mounts the electric device 40, a mounting detection unit 30 that detects that the electric device 40 is mounted on the mounting portion 32, and the electric device 40. Is mounted on the mounting portion 32, and includes a pair of output terminal portions 33 </ b> A for contacting a charging terminal 41 provided in the electric device 40 and applying a charging voltage to a secondary battery built in the electric device 40. . The output terminal portion 33 </ b> A is disposed in the case 31 and is provided so as to protrude from the terminal window 35 provided in the case 31 to the mounting portion 32. The mounting detector 30 is pivotally supported in the case 31, and a tilting body 34 in which a protruding portion 37 at one end passes through a through hole 36 provided in the bottom surface of the mounting portion 32, and a protruding portion 37 of the tilting body 34. And a spring wire 33 for urging the projection in the protruding direction. When the electrical device 40 is mounted and one end of the tilting body 34 is pushed down against the urging force of the spring wire 33, the output terminal portion 33A is moved from the terminal window 35 to the mounting portion 32 in conjunction with the rotation of the tilting body 34. Extrude and contact with the charging terminal 41 of the electric device 40.

  Furthermore, this charging stand divides the tilting body 34 of the mounting detection unit 30 into left and right and independently supports the rotation. By pressing the left and right tilting bodies 34, the output terminal portion 33A is pushed out from the terminal window 35 to the mounting portion 32. Since the charging stand having this structure independently tilts the respective tilting bodies 34 divided into the left and right, only when the tilting bodies 34 on both the left and right sides are balanced and pushed down with an equal force, the two output terminal portions 33A are arranged. Stably contacts the charging terminal 41 of the electric device 40. When the tilting bodies on the left and right sides are pushed down unbalanced, there is a drawback that both output terminal portions cannot be stably brought into contact with the charging terminal of the electric device. In addition, this charging stand has a drawback that it is difficult to reliably charge the output terminal portion 33A by contacting the charging terminal 41 of the electric device 40 over a long period of time. This is because the output terminal portion 33A and the charging terminal 41 cannot be reliably contacted with each other due to the surface or dirt. Furthermore, the charging stand having the above structure also has a drawback that the mechanism for projecting the positive and negative output terminal portions 33A becomes complicated.

  As a structure for avoiding such drawbacks, a charging base having a structure shown in FIG. 21 (Patent Document 2) and a structure shown in FIG. 22 (Patent Document 3) has been developed. The charging stand shown in FIG. 21 is connected to a case 45 having a mounting portion 42, a pair of spring wires 43 having terminal portions, and the respective spring wires 43 so as to be tiltable in the case 45. A pair of tilting bodies 44 are provided. The tilting body 44 is provided with a projecting portion 47 at one end and the other end as a connecting end 48. The connecting ends 48 are tiltable to each other and are movably connected in the longitudinal direction, and a pair of tilting bodies 44 are arranged in a straight line. is doing. Each tilting body 44 is provided with a spring wire 43 constituting a terminal between the fulcrum and the connecting end 48 with the middle as a fulcrum so that the same lever ratio is obtained. In the charging stand, when the electric device 20 is not mounted, the protruding portion 47 protrudes to the mounting portion 42, the tilting body 44 sets the terminal portion of the spring wire 43 to the retracted position in the case 45, and the electric device 20 is mounted. When the projecting portion 47 is pushed, the tilting body 44 tilts and the terminal portion of the spring wire 43 projects to the mounting portion 42 of the case.

  22 includes a spring wire 53, a tilting body 54, and a seesaw piece 55. The charging terminal shown in FIG. In the charging device, when the portable device is not attached to the attachment portion, the seesaw piece 55 causes the protruding portions 57 at both ends to protrude from the attachment portion, and the tilting body 54 sets the output terminal portion to the retracted position in the case. Further, in a state where one projecting portion 57 of the seesaw piece 55 is pushed into the case and the other projecting portion 57 projects into the mounting portion, the tilting body 54 retracts the output terminal portion into the case. It is said. Furthermore, when the portable device is mounted on the mounting portion and the protruding portions 57 at both ends of the seesaw piece 55 are pressed, the seesaw piece 55 presses the tilting body 54 in the middle to cause the output terminal portion to protrude outside the case.

  The charging base having these structures is effective in a charging base in which the terminal portion and the pressing portion are provided on the same side, but the terminal portion and the pressing portion are provided at different positions, for example, two orthogonal sides. It cannot be applied to a charging stand. Particularly in recent years, due to design requirements, charging terminals of electrical devices are often provided on the side surface instead of the bottom surface side, and a flexible structure that can cope with such a structure is required.

  Further, all of the above charging bases have a structure in which the protruding portion is pushed down by insertion of an electric device, and the spring wire is pushed up by rotating around the pivot shaft. For this reason, in any charging stand employing these structures, the spring wire immediately protrudes in conjunction with the depression of the protruding portion. As a result, in an arrangement in which the position of the projecting portion and the spring wire are close in structure, the spring wire may project substantially simultaneously with the depression of the electric device.

  However, depending on the mode of setting the electric device on the charging stand, for example, the electric device may be set while sliding on the upper surface of the charging stand. In this case, the protruding portion is pushed down to protrude the spring wire. When the electric device is slid, the protruding spring wire comes into contact with the surface of the electric device and scratches, which may cause a scratch. In particular, such a state becomes conspicuous in a state where the electric device is set vertically.

  The present invention has been made in order to solve the conventional problems as described above, and its main object is to provide a charger that can avoid a situation in which the surface of an electrical device is damaged by a protruding terminal when connected to the electrical device. Is to provide.

The case 1 is tiltably attached to the case 1 via the first tilting shaft 9A, and is tilted by the slide of the slide end 16a, and at the same time with respect to one charging terminal 21 of the electric device 20 mounted on the mounting portion 2. For electrical connection The first tilting portion 4A provided with one protruding terminal 3A, and the case 1 are tiltably attached to the case 1 via a second tilting shaft 9B provided apart from the first tilting shaft 9A, and the first tilting Linked with the part 4A, tilts in a substantially symmetric posture according to the tilt of the first tilting part 4A, and is electrically connected to the other charging terminal 21 of the electrical device 20 mounted on the mounting part 2 And a second tilting portion 4B provided with a second projecting terminal 3B, and the projecting portion 7 is pressed when the slide portion 16 mounts the electric device 20 on the mounting portion 2. Then, the slide end 16a tilts the first tilting part 4A and the second tilting part 4B linked to the first tilting part 4A, and the first projecting terminal 3A and the second projecting terminal 3B are connected to the charging terminal 21, respectively. Can be configured to Thereby, the operation | movement which mounts | wears a mounting part with an electric equipment is utilized, the slide movement by a slide part is converted into a tilt, and the advantage which can connect a protrusion terminal to the charging terminal of an electric equipment reliably is acquired.

  Further, according to the charging stand according to the second aspect, the first protruding terminal 3 </ b> A from the timing at which the protruding portion 7 starts to be pressed when the slide portion 16 mounts the electric device 20 on the mounting portion 2. And the delay means which delays the timing which connects the 2nd protrusion terminal 3B to the charging terminal 21, respectively can be provided. As a result, when the electrical device is mounted on the mounting portion, the first projecting terminal and the second projecting terminal are not projected immediately, and the projecting timing is delayed so that the first projecting terminal and the second projecting terminal The situation where the surface is unintentionally damaged can be avoided.

As shown in FIG. 6, FIG. 7, etc., the entire slide portion 16 is L-shaped, and a rear end is bent to form a slide end 16a. By curving or chamfering the front end of the slide end 16a, the slide end 16a can smoothly come into contact with the tilting end 17 of the first tilting portion 4A described later. The slide end 16a is urged by a spring or the like in the direction in which the protruding portion 7 protrudes, and as shown in FIG. The terminal 3A and the second protruding terminal 3B are accommodated. The slide portion 16 is integrally molded with a resin such as plastic having excellent insulation.
(Protrusion 7)

In this example, two protrusions 7 are provided. By providing a plurality of protrusions 7, more stable operation can be expected. However, it goes without saying that the number of protrusions can be one, or three or more. Moreover, the protrusion part 7 makes the surface contact | abutted with the electric equipment 20 the inclined surface 7a. As a result, when the electric device 20 is mounted on the mounting portion 2, the protrusion 7 is pushed so that the edge portion of the electric device 20 slides downward along the inclined surface 7a. The movement in the vertical direction can be converted into a horizontal movement of the slide unit 16. Further, as described above, the protruding portion 7 and the slide end 16a are arranged so as to intersect with each other by about 90 °, as shown in FIGS. 6, 7, 8, and 9. Thereby, the operation on the short-side peripheral wall 24, that is, the bottom surface side of the electric device 20, can be converted into the operation on the long-side peripheral wall, that is, the side surface side of the electric device 20.
(Delay means)

  This slide portion 16 is a delay means for delaying the timing of connecting the first protruding terminal and the second protruding terminal to the charging terminal from the timing at which the protruding portion 7 starts to be pressed when the electric device is mounted on the mounting portion. Is configured. In other words, when the electric device is mounted on the mounting portion, the protruding terminal is not immediately protruded, but the protruding timing is delayed. By doing in this way, it can prevent damaging the surface of an electric equipment unintentionally with a projecting terminal. As such a delay means, specifically, as in the conventional structure shown in FIGS. 20 to 22, the pushing operation of the projecting portion 7 is not directly transmitted to the tilting body provided with the projecting terminal, but once the slide portion 16. In addition, by making the slide portion 16 have a long stroke, a mechanism for converting the pushing operation through the slide portion 16 into a tilting operation is generated, and the operation is delayed. Thus, with a relatively simple configuration in which the slide portion 16 is added, a delay in the protruding operation of the protruding terminal can be added, and the protection function of the electric device can be effectively added.

  Moreover, according to the structure which adds the slide part 16 in this way, by changing the length of the slide part 16, from the timing which the protrusion part 7 is pressed, a 1st protrusion terminal and a 2nd protrusion terminal are charging terminals. The delay time until the connection timing can be adjusted. Furthermore, this also has an advantage that a delay time corresponding to the length of the charging base can be set by appropriately selecting the length of the slide portion 16 even for charging bases having different lengths.

Further, a gap may be provided between the slide end 16a of the slide portion 16 and the tilt end 17 of the first tilt portion. By providing a gap in a normal state where no external force is applied, i.e., the electric device is not set, a delay is caused by the gap until the projecting portion 7 is pushed by the electric device and the tilting body 4 starts to operate when mounted. it can. Thereby, the timing which a protrusion terminal protrudes can be delayed, and it can avoid that the surface of an electric equipment is damaged with a protrusion terminal.
